Mean Well HLP-80H-42 PCB Power Supply 80W 42V 1.95A

This model is intended for built-in LED lighting systems where an AC-DC open frame power supply is needed. It is positioned for OEM and B2B use cases that need an 80W-class internal power unit rather than a finished external adapter.

The HLP-80H-42 supports universal AC input from 90-305VAC and also lists a 127-431VDC input range. That wide range makes it suitable for projects that need flexibility across different mains conditions.

This model includes short circuit, over current, over voltage, and over temperature protection. The product data states short circuit protection uses hiccup mode with automatic recovery after the fault is removed, while over current protection uses constant current limiting.

It is rated for operation from -40°C to +70°C, subject to the published derating curve. The description also states it is suitable for dry and damp locations, which helps for indoor commercial and industrial lighting environments.

The HLP-80H-42 is an open frame design that cools by free air convection, so it does not rely on an internal fan. It is a better fit for embedded designs where compact size, low weight, and integration into a larger system matter more than a standalone enclosed housing.

The product data lists UL8750, CSA C22.2 No. 250.0-08 for certain versions, BS EN/EN61347-1, BS EN/EN61347-2-13, and EAC TP TC 004 approvals, with design reference to UL60950-1. Mean Well also lists a 3-year warranty for this model.
